when I build my project I have this warning:
ld: warning: instance method 'shareMessage' in category from /Users/attiliopatania/Library/Developer/Xcode/DerivedData/.../Objects-normal/armv7/Place+Factory.o conflicts with same method from another category
I'm not be able to understand where is the issue with the structure I report to you, maybe I make a mistake on using the categories This issue born when I force myself to use the pattern of @class declaratin on .h file and #import of the useful headers class witinh the .m I hope that somebody can help me :)
shareMessage is a method declared within the class Bean.h that is parent for Place+Factory in this way:
Place+Factory.h
#import "Place.h"
@interface Place (Factory)
...
@end
Place+Factory.m
#import "Place+Factory.h"
#import "User+Factory.h"
@implementation Place (Factory)
...
- (NSString*) shareMessage{
return @"myMessage"
}
...
@end
NB: User+Factory have the same structure of PlaceFactory and it is a child of Bean too.
Place.h
#import "Bean.h"
@interface Place : Bean
...
@end
Bean.h
#import <Foundation/Foundation.h>
#import "HttpFunction.h"
#import "Usefull.h"
#import "AppManager.h"
@interface Bean : NSObject
...
- (NSString*) shareMessage;
@end
Bean.m
#import "Bean.h"
@implementation Bean
...
- (NSString*) shareMessage{
return [self.class description];
}
...
@end
updated: at the end I solved. I review all my classes handling where possibile @ class within the .h files and the # import order within the .m files (that it seems to be the real issue).
